IMPROVEMENT IN WASHING-MACHINES.

Specification forming part of Letters Pat-cnt No. 139,5ll, dated J une3, 1873 application filed V November 21, 1872.

To all 'whom it may concem:

Be it known that I, MELVIN N. LOVELL, of

the city and county ot' Erie and State of Pen nsylvania, have inventedcertain Improvements in Wa-shing-Machines, of which the following is aspecification:

i end View with a part of the upright piece broken away to show theworking of the machine more perfectly. Figs. 3 and 4 are views of thejournal-boxes and pieces around which the springs are coiled. Figs. 5and 6 are views ot' the pieces which I use in attaching it to a tub orbox.

The frame-work is composed of the pieces A A, uprights B B, and toppiece G. Within this frame are hung the corrugated roller D and thesmooth roller E. The journals of the smcoth roller run in holes in theuprights B B, which holes may or may not be bushed with metal. Thediameter ofthe smooth roller is such that it fills the space between thepieces A A as nearly as possible without preventing its free revolutionthis is to prevent the clothes from winding around it. The journals F Fot' the corrugated roller D pass through slots in the uprights B B, andhave their bearings in journal-boxes I I. To one ot' the journals isattached the crank II, through which motion is imparted to the machine.The journal-boxes I I are provided with projections K K, which projectpast the edges of the slots in the uprights B B and engage the innersides ot' them. These prevent the journal-boxes from sliding out oftheir places toward the outside ot' the machine. The ends ot' thecorrugated roller D prevent them from sliding inward. The journal-boxesare also provided with rods L L, which pass 'up through holes in the toppiece G. Around the rods L L are coiled the springs M M, the upper endsof which rest against the top piece u C, and the lower ends against thejournalboxes I I, thus bringing their pressure to bear on the corrugatedroller D, and through it on the clothes as they pass between it and thesmooth roller E. The pieces A A eonstitute an important partof theframework. Their elongations past the uprghts B B serve as convenientmeans to fasten the machine :oa common wash-tub or box, and they preventthe clothes from winding around the smooth roller E. They are soattached to the uprights' B B that their upper edges shail be on alinewith the center of the roller E; At the places where they are attachedtothe up-ignts B B they are grooved so as to receive the edges ot' theuprghts B B, the grooves being made deeper at their loweredges, as shownby the dotted lines in Fig. 2. This` is to bring their lower edgesnearer t'gether, to ina-ke them more useful in securing the machine to atub or box. e

To festen the machine to a tub or box 1 use the pieces shown at Figs. 5and 6, which I make from Wood, but they may be made of metal. Thesepieces are screwed to the inside of the tub or box, as shown at Fig. 1.The

machine is put into the astening by first put` ting the ends of thepieces A A next to the crank onto the piece N, then letting the opi notconfine myself to the use ot' the smooth' roller E, but may substitutefor it any other kinds of a roller or series ot' rollers.

What I claim as new is as follows:

The combination of the pieces A, the` uprights B, the top piece U, thejournal-boxes I with projections K, rods L, and springs M, rollers D E,tub F, and pieces N O, as and for the purpose specified.
